Nordic telecoms giant TeliaSonera is at the heart of several international corruption probes involving its activities in Uzbekistan. Now it says it may have broken the law in neighboring Kazakhstan and other countries, as well.

An external review of TeliaSonera's dealings in five countries has found that “several transactions, and actions during [2007-2013] have been conducted in a manner inconsistent with sound business practice and TeliaSonera’s ethical requirements,” board chair Marie Ehrling told an Annual General Meeting on April 2.

“It cannot even be ruled out that certain conduct has been in violation of the law,” she said.

The review, commissioned last April and conducted by international law firm Norton Rose Fulbright, covered Nepal, Kazakhstan, Azerbaijan, Tajikistan, and Georgia but focused mainly on the first three countries.
